Why won't my Toro 74945 starter crank?

  Jennifer ReyesAug 28, 2025
  If the starter on your Toro Lawn Mower doesn't crank, there are several possible reasons. First, ensure the blade control switch (PTO) is disengaged and the parking brake is set. Also, make sure the drive levers are in the neutral lock position and that you are seated on the seat. If these aren't the problem, check if the battery is dead and charge it if necessary. Inspect the electrical connections for corrosion or looseness, and replace the fuse if it's blown.

Why don't the blades rotate on my Toro 74945 Lawn Mower?
- K
  Katrina BennettSep 10, 2025
  If the blades on your Toro Lawn Mower aren't rotating, it could be due to a worn, loose, or broken mower deck belt, the mower deck belt being off the pulley, a worn, loose, or broken pump drive belt, or a broken or missing idler spring. Try installing a new deck belt, installing the mower deck pulley and checking the idler pulley, idler arm, and spring for correct position and function, checking the belt tension or installing a new belt, and replacing the spring.

  If your Toro Lawn Mower isn't driving, first check that the bypass valves are closed tight and tighten them if necessary. Also, inspect the pump belt for wear, looseness, or breakage and change the belt if needed. Ensure the pump belt is properly on the pulley. A broken or missing idler spring could also be the problem; replace the spring. Finally, check the hydraulic fluid level and temperature; add hydraulic fluid to the reservoirs or let it cool down.

How to fix a Toro Lawn Mower engine that loses power?
- G
  gharrisonAug 26, 2025
  If your Toro Lawn Mower engine is losing power, it could be due to several reasons. First, check if the engine load is excessive and reduce the ground speed. A dirty air cleaner can also cause power loss, so clean the air-cleaner element. Ensure that the oil level in the crankcase is adequate, adding oil if necessary. Additionally, inspect the cooling fins and air passages above the engine for any obstructions and remove them. Lastly, the vent hole in the fuel cap may be plugged, so clean or replace the fuel cap.
